0–100, higher is better. How it is calculated

Nakladatelství Karolinum is the official publishing house of Charles University, specializing in academic and scientific publications including books, journals, and monographs. The website reflects a well-established university press with a clear focus on humanities and sciences, targeting academics, students, and researchers. The business model revolves around publishing, distribution, and an e-commerce platform for book sales. The domain age and WHOIS data confirm a long-standing presence consistent with the university affiliation. Technically, the website uses a custom CMS with modern JavaScript libraries such as jQuery, TinyMCE, and bxSlider. It integrates Google Analytics and Google Tag Manager for tracking and marketing purposes. The site is mobile optimized with good SEO practices but lacks some advanced accessibility features. Performance is moderate with room for improvement. From a security perspective, the site enforces HTTPS and uses a cookie consent mechanism, indicating basic privacy compliance. However, it lacks explicit privacy policies, terms of service, security headers, and vulnerability disclosure mechanisms. No critical vulnerabilities or WAF blocking were detected, suggesting a stable security posture but with opportunities for enhancement. Overall, the website is professional, trustworthy, and well-aligned with its academic publishing mission. Strategic improvements in privacy documentation, security headers, and incident response transparency would strengthen its compliance and security posture.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

6 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Nakladatelství Karolinum holds a strong market position as the university press of Charles University, leveraging its academic reputation to publish specialized scholarly content. Its competitive advantage lies in its affiliation with a prestigious institution and a broad catalog of academic books and journals. Revenue streams likely include book sales, journal subscriptions, and printing/distribution services. The target customer segments include university students, faculty, researchers, and academic libraries. The partnership ecosystem includes related e-commerce platforms and distribution channels. Growth indicators include active content updates, event calendars, and social media engagement. The company operates primarily in the Czech Republic with a medium organizational size.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and cookie consent implemented. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No vulnerability disclosure or incident response contacts are provided, which limits transparency and readiness. Data protection practices are basic, with no explicit privacy policy found. The site does not expose sensitive data or use vulnerable libraries visibly. Overall, the security posture is stable but could benefit from enhanced policies and technical controls to meet higher compliance standards such as GDPR and NIS2.

Recommendations

  1. Implement and publish a comprehensive privacy policy and terms of service to improve GDPR compliance and user trust.
  2. Add security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against web vulnerabilities.
  3. Establish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting and incident response.
  4. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  5. Conduct regular security audits and update third-party libraries to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a custom CMS platform using modern JavaScript libraries like jQuery, TinyMCE for rich text editing, and bxSlider for UI sliders. It integrates Google Analytics and Google Tag Manager for analytics and marketing. The site is mobile responsive with good SEO meta tags and Open Graph data for social sharing. Performance is moderate, with potential improvements in loading speed and accessibility. The absence of common security headers and limited accessibility features indicate areas for technical enhancement. Overall, the infrastructure supports the business needs but would benefit from modernization and security hardening.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
